To u/Z Lelio/1L 'it may concern.'

le it known that I, Josera W. alumina, a citizen o'f the United States, residing at- Forest. in the county of Lewis. State ot' ll'ashington` have invented certain new and uselul improvements in Cow-Tie Locks; and l do hereby declare the following to be a tull. clear. and exact description olf the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to locks.

'l'he primary object ot the invention is to provide a device ot this character adapted to be employed in connection with a halter, or to connect two chains tor securing a cow or other animal within its manger or stall so as to permit the animal to be readily turned loose as for instance, in case of tire.

Another and important object of the in vention is toin'ovide a simple, novel and improved form ot' lock Jfor use in connection with a chain. halter or other tying device having one section permanently connected to the lock while the other section is rcmovablv secured thereto. l

lVith the above and other objects in view, the inlvention consists of certain other combinations and arrangements ot' parts as will be hereinafter more fully described, claimed and illustrated in the accompanying drawings. .in which:

Figure l is an enlarged longitudinal sectional view ot' the lock and portions of a chain halter connected therewith. the shackle ot the lock heilig in a closed position. Fig. -is a similar iew but showing the shackle rel iased Yt'rom the bolt o't the lock for disconnecting an end ot' the tie loop. Fig. 3 is a plan ew ot the lock. Fig. Ii is a cross sectional view on the line (-t oit` Fig. 1.

My improved lock is illustrated in connection with chain sections, indicated by the numerals il and it.

The lock comprises a main bar or fiat body member lil which is loi'fnrcated at one end to torni a pair ot' spaced apertured ears 20 between which one extremity of a bow- .shaped shackle 2l is pivoted upon a pin 22 and has its notched `tree end movable toward and away troni they Vopposite extremity of the bar in moving to a locked or unlocked position. Connected to the bar 19 is the lock casing which eoinpiises the side plates 23 which are riveted to the bar as shown at 24.

The edge portions ot the easing are'closed by a tlat strip ol metal 25 which is secured to the bar 1i). as shown at 2G, and is also t'ormed with a hearing 2T, for securing the 'lree extremity ot` the chain section 1.4L to the lock through the medium ot' a clevis or loop 2S which has the extremities of its leg portions engaged upon opposite sides of the bearing. and is dctachably and pivotally connected thereto blv means ot a removable pin 2.) retained in position by a key 30. The edge strip 25 is bent in substantially U-orm so that its bight portion ll is spaced from the adjacent ends ot' the bar and plates while the top portion $32 ol the strip is bent inwardly at right angles at its torward end and the extremities of the strip are riveted to the bar by a eonnnon fastening member Bil. .said right angularly bent portion forming the inner ond -t of the casing.

'lhe casing is provided with a cent-ral longitudinal slot 35 while mounted within the 4casing is a sp1'ing-:n'tuated hollow' catch member ilo. the same comprising a single strip ot sheet metal bent at right angles at three points to Vt'orm a substantially U- shaped, member having a -forward fingenengaging end or leg Sli' communicating with the space inclosed b v the bight portion "ot' the edge strip. while the inner cud or leg 28 extends in the direction ot said bight portion and extends across the slot 235, as shown at Z39. The catch member -lt' is held in its normal operative position by means ol" a coiled expansion spring lo disposed between the inner end ol the bolt and the inner end wall ot the casing. whereby the curved free end of the shackle may be moved into the slot for automatically engaging the inner end of the portion 35) with a notch -l1 in said end ot the shackle while said t'ree end of the shi'ickle extends into the hollow catch 1nember. ln this operation ot engaging the shackle with the, bolt. the spring l0 will give sulliciently to allow the inclined end of the shackle. to ride over the end of the portion 3f), and the spring will then force said end into the notch for securely holdingl one of the cirenlar links lT between the shackle, and the bar at their pivoted ends. By slight pressure against the engaging' portion 3T forward end of the portion 3.) is disengaged from the notch Ll-l. thereby freeing the shackle so that a slight pull upon the chain section 16 will open the loop. The hight portion ot` the edge strip of the casing prevents accidental depression of the bolt, but

such depression can be readily accornilshe by manual application of force pro* rly dirented by placing a finger Within the. loop or bight nortion and pressing against the element 2 A transverse pin l2 is carried by the casing to limit the movemento'f the cluteh member 36.

IIt Will be seen that I have provided a device of this character which is fully capable of attaining the foregoing objects, in a thoroughly practical and effective manner.

' l do not limit my invention to the exact details of construction, combination and arrangement of parts, as herewith illustrated and described, but my invention may only be limited by areasonable interpretation of the claim.

l claim ln a lock, a body member, a hollow casing secured to the body member and provided foeavoo With a loop and with a longitudinal slot, a hollow catch member slidable Within the easing and having an element extending across said slot, means for holding the hollow catch member normally with its lower side exposed Within 'the inclosu-re of said loop,

said catch member being protected'against accidental displacement by said loop and adapted to be moved by a nger of a person extending into the loop, and a shackle pivotally connected to the body member and adapted to be swung into such position 'that its free end extends into the hollenl catch member and engages therewith.
